Are there many tiny files? They may take 4KiB of space each even though they're less than a KiB big (https://en.wikipedia.org/wiki/Disk_sector https://en.wikipedia.org/wiki/Disk_sector). On a SanDisk portable SSD I own, the cluster size is even 4MiB. If you put a node modules directory in there with thousands of tiny files, it can "take up" several GiB of space.
